P0D0DBattery Charging System Positive Contactor A Control Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D0D means the control line of positive charging contactor A sits too high, typically from a short to a supply voltage or a driver that no longer switches off. The coil may then stay energised, so the contactor could close without a command, which the module has to prevent. No manufacturer documents P0D0D publicly; on the Chevrolet Volt GM folds the short to power into P0D0A and flags it when the off-state output stays within 0.4 V of supply. CARB requires plug-in vehicles to monitor charging components. Causes are crossed or chafed wiring and a failed driver inside the control module. Low readings are P0D0C, opens P0D0A, a welded contactor P0D08. The system normally blocks charging until the fault is gone.
